Clutch sticking half way to floor

huudoo

I talked to a gtr tech@ local nissan today , he said most likely the clutch master cyl.
that the piston/ valve in the mc was not opening all the way ,
to enable enough pressure to get pedel to come all the way up... if so it would be cheaper
to just put a mc on and add the motul rbf 600 I bought today.. in stead of just flush
the fluch would be $100.00 -- the mc is 138.00 plus labor $150.00 including a bleed and
my motul ....my car only does it when it is really hot and spirited driving....

or I could just wait and drive it normal and see what happin's
